TNMG 110304 T5125 indexable turning insert — Tungaloy, CVD‑coated carbide for turning

A TNMG 110304 T5125 indexable turning insert designed for external and internal turning, optimised for cast iron and interrupted cuts

• CVD-coated carbide for enhanced wear resistance
• Optimised for interrupted cuts in cast iron
• 0.4 mm corner radius for versatile edge strength
• Double-sided chipbreaker; reversible insert

Reliable machining under interrupted and less stable conditions

The TNMG110304 insert is manufactured as an ISO‑standard triangular indexable cutting insert and is intended for turning operations where stability varies or interruptions occur. The combination of a CVD-coated surface layer and a tough carbide substrate delivers a balance between edge retention and resistance to chipping, which reduces tool changes and unplanned downtime. Specified geometry — including the 0° clearance angle and the 0.4 mm corner radius — promotes consistent cutting forces, improving dimensional repeatability when external and internal contours are being machined.

Material and coating explained for predictable tool life

The grade T5125, a CVD‑coated carbide specification, has been formulated for tougher performance when machining cast iron under intermittency or less rigid setups. The coating increases thermal stability and abrasion resistance, while the tough substrate absorbs shock during interrupted cuts. As a result, wear progression is retarded and surface finish stability is improved; this leads to longer intervals between indexing and reduced tooling costs per component. Where surface appearance matters, a controlled wear pattern ensures predictable finishing passes.

Compatibility and secure mounting within ISO TNMG systems

Compatibility with a toolholder depends on insert form, clearance angle, tolerance class, fastening arrangement, size and thickness — all defined by the ISO TNMG system. This insert is triangular with a central hole (zylindrisches Loch) and is reversible thanks to its double‑sided design; the double-sided chipbreaker permits two cutting edges per index. Dimensionally, the plate thickness is 3.18 mm and the inscribed circle is 11 mm, so selection of a matching external holder or boring bar and the correct clamping set is essential for repeatable clamping force and accurate seating. Replacement screws and clamping pads form part of the system setup for safe operation.

Process benefits and practical application advice

Using a reversible insert with a dedicated chipbreaker reduces tooling inventory and simplifies logistics while maintaining cut control and evacuation of chips in interrupted turning. The insert’s geometry and T5125 composition make it efficient in roughing and semi‑finishing passes on cast iron, where stable chip formation and edge security are required. For best results, pair the insert with a suitably rigid holder and select cutting data that match machine capability; if there is uncertainty regarding feeds, speeds or holder choice, technical consultation is readily available — e‑mail info@metav-werkzeuge.com or call +49 2822 7131930 for tailored recommendations.

FAQ

What materials is this insert best suited for?
The Tungaloy TNMG 110304 T5125 insert is optimised for machining cast iron, particularly when interrupted cuts or less rigid setups are encountered.

Can the insert be reversed to use a second cutting edge?
Yes, the insert is double‑sided with a reversible chipbreaker design, enabling use of both cutting edges before replacement.

Which clamping and holder features are required for correct use?
A matching ISO TNMG holder that accommodates the 11 mm inscribed circle, 3.18 mm thickness and central cylindrical hole is required; correct clamping pads and screw torque ensure repeatable seating.

How does the T5125 grade affect performance?
The T5125 CVD‑coated carbide grade offers a tougher substrate with improved wear resistance, providing longer edge life and reliable performance under intermittent cutting conditions.

Is this insert suitable for finishing passes as well as roughing?
Yes; with appropriate cutting data and a rigid setup, the insert can be used for roughing and for semi‑finishing where controlled surface quality is required.
